Developing a Feature Extraction of Existing Structures Using an Ambient Vibration Test

The paper aims to extract the dynamic properties of existing structures without utilizing the analytical models. The ambient vibration testing could be used on any type of frame such as concrete, steeland masonry to investigate the structural vulnerability.The method could bethe first stage and necessarily forthe retrofit process. To achieve this aim, the ambient vibration testing can also be employed. The experimental data obtained from the methodcan be used to monitor the health, evaluating, and damage detection structures at present. The achieved datacan be comparedin future with the recorded signals at different times.
